SASH-BETAINER.

Specification of Letters Patent.

Application filed August 31,1920. Serial No. 407,150.

To all whom it may concern:

Be it known that I, JACOB A. Prr'rnNsnn, a citizen of the United States, residing at Millburn, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Sash-Retainers, of which the following is a specification.

This invention relates to retaining devices which are employed in connection with window-sashes and the like for temporarily retaining the same at any desired open position.

Some of the objects of the present invention are: to produce a device whose primordial use is the obviation of sash weights, cords, pulleys, etc, which is comparatively more thoroughly efficient and practical; to produce a device of the character mentioned which as to construction embodies a feature of adjustability by virtue of which the device may be kept in a proper working condition. 'With the foregoing and other. objects in view the invention resides in the particular provision and arrangement of parts hereinafter more fully described and illustrated in" the accompanying drawing, in which: r

Figure 1 is a vertical sectional view illustrating the device of the present invention. and showing the disposition of parts when the window-sash is in a closed position. a

portion of a window-sash and its frame being shown.

Fig. 2 is a detail sectional view illustratg the coaction of one of the grooved wheels and the flexible element forming parts of the device in the retention of the sash in an open position.

Fig. 3 is a face View of one part of the device which is preferably arranged upon the window frame.

at is a transverse sectional view taken on the line H of Fig. 1.

Fig. 5 is a transverse sectional view taken on the line 5-5 of Fig. 1.

Referring now to the drawing it will be manifest that, the device of the present invention in its construction, among other parts, consists essentially of a flexible element 10, and coaoting grooved wheels 11 which are yieldingly supported. The flexible element 10 is preferably arranged on the window frame, a portion of which is shown at 12. The grooved wheels 11 are arranged on the window-sash inasmuch as the flexible element 10 with which the grooved wheels 11 coact, is arranged on the window frame. The window frame is of such construction as to readily accommodate the flexible element 10 and correlated parts from which it directly receives its support. The element 10 is supported by a member 14 which is of a length to extend substantially the length of the runway in which the window-sash moves. Themember 1 1 is formed to provide a series of spaced grooved projections 15 on the back 16, and the member 14. is also formed to provide an attaching flange 1?. The flexible element 10 in correlation has one portion thereof, the portion 18, disposed over and supported by the projections 15-. The opposite extremities 19 and 20 of the element 10 are brought behind the back 16. A connector 21 connects the extremity 19 of the element 10 with a cap member 22 bythe employment of an adjusting nut :23. The cap member 22 is arranged over one end of a spring 24, and a cap member 25 similar to the cap member 22 has the opposite end of the spring 24 in engagement therewith. The connector 21 extends through an aperture in the cap member 25,

and through the convolutions of the spring A connector 26- connects the extremity 20 of the element 10 to the cap member 25 by the employment of an adjusting nut 27. The cap member 25 is arranged over one end of a spring 28 which surrounds the spring 24. The end of the spring 28 opposite tothat having-the cap member 25 arranged thereon, is in engagement with a cap 29 of the cylindrical case 20. The connector 26 extends through an aperture in the cap 29 and through the spring 24. By virtue of this arrangement of parts, it will be manifest that, the tension of the flexible element 10 may be regulated and adjusted at will.

The grooved wheels 11, which, as stated are arranged on the window-sash 13, for

coaction with the flexible element 10 in the retention of the said sash in the desired open position, are each yieldi'ngly supported by the employment of a case 31 having an attaching flange and slots 32. The opposite side walls 33 of the case 31 are each provided with a bead 34.. A wheel supporting member 35 carries the grooved wheel 11 be tween its spaced parts 36, and the pin 37 on which the wheel 11 rotates has the ends thereof disposed in the slots 32 so as to guide the wheel 11 in its inward and outward movements. The member 35 embodies a part 38 in the nature of a transversely arranged plate, whose opposite ends are cut out so as to receive the beads 34. Flat leaf springs 39 are positioned behind the member and normally exert outward pressure against the said member Each spring 39 has one end thereof secured as at 4L0 and its opposite free end disposed behind the part 38 in overlapping arrangement with each other. There may be employed any desired number of wheels 11, and in the present instance two wheels are employed. The cases 31 which carry the said wheels are sunk in the vertical stile of the windowsash. If desired the device of the present invention may be arranged on opposite sides of a Window frame and its sash.

From the foregoing it will be manifest that, as the windo sash is brought to a position in which the grooved wheels are disposed adjacent the unsupported predetermined points of the portion 18 of the flexible element 16, the said wheels will be moved outwardly under the action of the springs 39, thus causing the flexing oi the particular parts of the element 10 referred to-see Fig. 2-with the result that the sash 13 will be temporarily retained in the desired open position. Under the arrangement of the parts the sash 18 may be readily raised and lowered, and the mechanical coaction of the parts has been found to be practicable to the point or being thoroughly effective.

The use of a iiexible element without springs such as the springs 2d and 28 has been found to be satisfactory, and such use may be adopted in the practice of the present invention.

What is claimed is:

1. In a device as characterized for use in connection with a window-sash or the like, a flexible element lni'lexibly supported at certain points in lts length, and means on I means including yieldingly mounted grooved wheels which are adapted to coact with said flexible element to flex the same as and'i'or the purpose specified. 1

Q retaining device including a flexible element fixedly arranged, means for varying the flexibility of said element, and shiftable means including yieldingly mounted grooved wheels which are adapted to c-oact with said flexible element to flex the same as and for the purpose specified.

4:. A device as characterized including the :ombination with a window-sash and a frame, of a flexible element, a support for said element, said support embodying attaching extensions and spaced projections which support portions of said element against flexing, and means including grooved wheels engageable with said element and capable of flexing the element at points between the projections.

A device as characterized including the combination with a window-sash and a frame, out a flexible element, means for supporting said element against being flexed at certain points and allowing the flexing thereof at certain points, yieldable means for varying the flexibility of said element, the said element being supported on said frame, and means including yieldingly mounted grooved wheels which are adapted to coact with said element to flex the same, he last mentioned means being carried by air window-sash.

testimony whereof I hereby aflix my si ature. I

JACOB A. PITTENGER.
